Summary
Bacteriophage T4 DNA containing cytosine has been obtained from cells infected with phage mutant in genes 42, 56,denA anddenB. This DNA can be cut by a number of restriction endonucleases. Fragments obtained by digestion of this DNA withEcoRI have been cloned using the vector plasmid pCR1.
Clones containing T4 DNA were identified by hybridization with radioactive early and late T4 RNA. A simple marker rescue technique is described for the genetic identification of the cloned T4 fragments. Some of the T4-hybrid plasmids which contain entire T4 genes can complement temperature sensitive and amber mutants of T4.
